7 Claims.

This invention relates to a machine for decorating and/or trade-marking paper, cardboard and the like.

The invention has for an object the construc-.

tion of a machine to decorate and trade-mark papers of various weights, particularly Wrapping paper with all-over designs and individual trademarks. I

. Still further the invention contemplates an arrangement whereby the all-over designs are of a two-tone or transparent efiect with certain sections blank and trade-marking imparted within said blank sections. 0

Still further the invention proposes a process of the class mentioned which. is characterized by causing a large engraved or embossing element to decorate by embossing and/or heat embossing the material, associating asmall replaceable en graved or embossing element with said large engraved or embossing element, and causing said small replaceable engraved or embossing element to trade-mark said material, in synchronized relation with the decorated portions from said enlarged'engraved element.

Furthermore es -another object of. this invention it isproposed to provide an embossing machine with a large engraved roller and an opposed large rol1er, and a variable engraved small trademarking roller associated with said embossing machine and said opposed roller, and synchronizing with the operation of said large engraved roller. V v

As another object,- it is proposed to so arrange the trade-marking roller on the embossing -machine and eitherthe trade-marking. roller and the embossing machine may be used selectively separately, or together.

Still further the inven 'on contemplates an arrangement whereby th'e large engraved roller produces a two-tone effect upon the material treated A very important feature of this invention is the economical trade-marking of papers and I other material in comparison with embossing .methods now used wherein the design rollers are engraved with all-over design and are also engraved with the trade-mark pattern. This old method of decorating papers is very expensive in that the manufacture'of the large roller with the all-over design and the trade-mark patterns limits the use of this roll tothe individual owner of the trade-mark a separate r011 being required for each user therefore production of small quantities of material cannot be economically produced.

present invention it is possible to manufacture the large engraving rollers with all-over designs left blank on certain areas for receiving the trademark impressions and from another sourcesupplying the trade-mark impressions.

A further point of importance according to this invention is that the engraved relays or shells can be used separately without the decorating where simply trade-marking is required without an all-over background design or the decorating embossing may be done without trade-marking.

Still. further the invention proposes the construction of a machine as mentioned which is simple and durable and which may be manufactured and sold at a resonable cost.

For further comprehension of the invention,

and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure:

Fig. 5 is a fragmentary elevational view of the lar e engraved roller of the embossing machine, P 1 5 Fig. 6 is an elevational view of one of the replaceable or exchangeable, relays or shells upon the trade-marking roller according to this invention.

The machine according to this invention com prises a conventional embossing machine having a large roller 10 engravedwith'an all-over design 11 and having blank areas 12 so as not to produce any impressions at certain areas. large roller works in conjunction with an opposed roller 13. The embossing machine is shown to have a rewinding roll 16 supported at each end on a bracket mounted on the main frame 14.. A material supply roll is supported at each end upon a bracket 17 moun-ted on the frame 14. i 1

A driving belt indicated by the dot and dash lines 19, connects with a main pulley 20' of the machine which is associated with the clutch mechanism 21 operated by the control levers 22. A gear 23 is associated with the pulley 20 and is provided with a belt 24 driving a wheel 25 connected by gear mechanism 26 with the shaft of the rewinding roll 16. The web of the material from the roll 18 passes over the tensioning mechanism 2'7 and then at the point 28 passes between the rollers 10 and 13 continuing around a portion of the roller 13 to another tensioning mechanism 29 and from there to the rewinding roll 16.

The large engraved roller 10 is mounted at each end upon a standard 30 adjustably mounted on the frame 14 and adapted to be adjustable by reason of an adjustably mounted screw 31 connected therewith and provided 'witha control hand wheel 32. The other'details (as for example the heating' means'for the rollers 10, etc.)

of the embossingmachine are not given in this specification since such details are generally known in the art at the present time andform no part of the invention. The embossing machine will readily be recognized bythe cursory description given. f

According to this invention an attachment is associated with the embossing machine to accomplish the trade-marking and comprises a trade-marking roller 37 supported at each end on a bearing 34 adjustably mounted on a bracket 33 attached upon theframe 14 of themachine. An adjustably mounted screw35 is associated with each bearing 34' and is provided with a hand wheel 36 so that the position of the standards 34 may be adjusted. The trade-marking roller is small, engraved and is adapted to act against that portion of the web of the material which is upon the roller 13.

The variable trade-marking roller '37 comprises a mandrel 38 which is formed with a central hollow or bore 39 connected with a steam control system 40. t0 produce the necessary heat for the trade-marking. Details of the steam control system will not be given here since the system does not involve invention and is according to the customary form. The mandrel 38 is formed with an enlarged portion 41 ,near one end. Traction collars 42 are mounted upon the mandrel and between these collars "several interchangeable and removable engraved relays or shells 43 are mounted. A removable collar 44 is threadedly engaged upon the mandrel 38 at the other end and together with the enlarged portion 41 serves to hold the shells 43 and'the collars 42 in place. The mandrel 38, the traction collars 42 and the shells 43 are provided with a key arrangement 45 so as to cause unitary rotation of these parts. The relays or shells 43 may .The

tating the hand wheel57. This causes the worm pinion to turn and correspondingly turn the the relation of the gear to the shells 43 so that the registering of the trade-marking may be adjustable. More particularly the gear 48 is keyed at 50 upon a bracket 51 which is rotative on a reduced portion 52 of the trade-marking roller 37.

A pair of spaced lugs 53 projects from the bracket 51. A shaft 54 is rotatively mounted through the lugs 53. A worm pinion 55 is fixed upon the shaft 54 by a pin 56. A handle 57- is fixed upon the shaft54 b'y'a pin 58. The worm pinion 55 is in mesh with a worm wheel 59 fixed upon the reduced portion 52 of the trade-marking roller 3'7.

Each of the relays 'or shells 42 are provided with one or more'raised portions 60 engraved with the trade-marks 61 adapted to register with the blanks on the material left by the areas 12 in the large engraved roller. The traction collars 42 are adapted to be in continuous contact with the enlarged engraved roller 10 so as to prevent concussion as the raised areas 60 move away from contact with the engraved roller 10.

The operation of the machine is. as follows: Rotations from the belt 19 are transmitted to cause the material to pass between the large engraved roller 10'and the opposed roller 13. The'large engraved roller 10 by ordinary heat embossing imparts its design upon the material except at the areas due to areas 12 of the large roller 10 which are left purposely blank for trade-marking. The raised areas 60 of the-trademarking shells 43 are arranged. to register with the blank areas upon the material and soimpress by ordinary heat embossing the trademark upon the material. It isthought that a detailed explanation of the exact operation of the embossing machine is' not necessary in view of the well known state of the art of embossing The main feature of this invention resides in the fact that small paper users may be economically served with this machine to trade-mark their papers. It is not necessary that a large engraved rollerlO be used for each customer. It is merely necessary that the small relay shells 43 be supplied for changing the trade-marking being imparted upon the material while the same large engraved all-over design roller be used for diiferent customers.

According to this invention, for small and large customers individual relays or shells are supworm wheel 59 fixed upon the trade-marking roller. Consequently the relation between the gear 48 and the trade-marking roller is adjust- I able so that the synchronizationof the trademark impressions and the all-over design can be readily controlled.

While I have illustrated and described my invention with some degree of particularity, I realize that in practice various alterations therein may be made. I therefore reserve the right and privilege of changing the form of the details of construction or otherwise altering the arrangement of the correlated parts without departing from the spirit or the scope of the appended claims.
